COUNTER-STlFFENER MACHINE.

SPECIFICATION forming part of Letters Patent No. 380,464, dated April 3,1888.

Application filed July 30.1887. Serial No 245,757.

To aZZ whom it may concern:

Be it known that I, CHARLES Lines TEN- NEY, a citizen of the UnitedStates, residing at Fitchbnrg, in the county of Viorcester and State ofMassachusetts, have invented a new and useful Counter-Stiffener Machine,of which the following is a specification.

My inventionrelates to improvements in counter-stiffener machines bywhich stiffcners are formed from blanks of leather and other materialsinto such shapes as are required in the manufacture of shoes; and theobjects of my improvements are to form counters in a more simple andexpeditious manner than has been done heretofore, and consequently tocheapen their cost. I attain these objects by the mechanism illustratedin the accompanying drawings, in which- Figure 1 is aside elevation ofthe entire machine; Fig. 2, a vertical section through the same on theline 1 2. Fig. 3 is a detail section, on an enlarged scale, of a portionof that outside of and on the line 3 4. Fig. 4 shows astifit'ener-blank,and Fig. 5 afinished stiffener.

shaped to rub the surface of the former-blocks in the wheel, and of suchlength as will reach the center line of former-blocks when pushed out toits farthest range of motion.

A spring, a, contained in a cavity of the sliding block, abutting at oneend the bottom of the cavity and at the other a cap, I), over the end ofa cylindrical screw, 0, in the closed end of the cell by which its forceis regulated, opposes with yielding resistance any pressure upon theouter end of the block.

The limit for the motion of the block is determined by the adjustmentofbinding-nuts against the outer end of the cylindrical screw 0, and upona rod, (2, which passes through the cylindrical screw 0, cap b, andspring a, fastening into the sliding block at the end of the cavity.

The side cellular bOXGS,'E E, are connected throughout their entirelength by a top cellular box, G, which is fastened upon them. The cellsin this box range on lines parallel with the plane of the wheel, withtheir axes on radial lines through the center of its face. The

What I claim, and desire to secure by Letters Patent of the UnitedStates, is

1. In a counter-stiffener machine, the combination, with the wheelhaving former-blocks upon its periphery, of the yielding sliding blocksand corrugated plates arranged with reference to each other,substantially as specified.

2. The combination, in a counter-stiffener machine, of the wheel 0,having former-blocks upon its periphery, with sliding blocks F and acorrugated plate H, substantially as specified.

3. The combination, in a counter-stiffenerv CHARLES LINUS TENNEY.
